针对1995年李登辉访美而开展的反分裂、反“台独”斗争

针对1995年李登辉访美,中国共产党、中国政府和全体中国人民开展了一场声势浩大的反分裂、反"台独"斗争。从广义上讲,这场斗争从1995年5月份开始,一直持续到1997、1998年中美两国元首实现互访,前后大致经历了四个阶段:1995年5月至1995年7月:从外交抗议到"四评六弹";1995年8月至1995年底:在与美方初步恢复接触的同时继续采取反击措施;1996年1月至1996年3月:围绕台湾地区领导人产生方式开展博弈和斗争;1996年4月至1998年底:适时将举行两岸政治对话提上日程,推动汪辜会谈再次举行,同时推动中美两国元首实现互访。至此,由李登辉访美引起的中美关系和两岸关系紧张的局面得到明显缓和,这场斗争取得了阶段性重大胜利。

Economic Evaluation on "Planting Three to Produce Four" High-yielding Project of Super Hybrid-rice in Hunan

The research conducted investigation and survey on 186 farm households in 2014 and carried out economic evaluation on ＂planting three to produce four＂ highyielding project of super hybrid rice. The results showed that the project of ＂planting three to produce four＂ performed significantly in terms of increasing yields and incomes. For example, per unit area yield of one-season late hybrid rice and middleseason hybrid rice proved the highest, and net income from middle-season rice in Longhui was the highest. It is obvious that to increase per unit yield is key for improving net incomes and to reduce machine fees and worker fees is crucial for decreasing fees.

Effect of dry density on the liquefaction behaviour of Quaternary silt

Quaternary silt is widely distributed in China and easily liquefies during earthquakes. To identify the influence of the dry density on the liquefaction behaviour of Quaternary silt, 40 cyclic triaxial liquefaction tests were performed on loose silt(dry density rd=1.460 g/cm^3) and dense silt(rd=1.586 g/cm^3) under different cyclic stress ratios(CSRs) to obtain liquefaction assessment criteria, determine the liquefaction resistance, improve the excess pore water pressure(EPWP) growth model and clarify the relationship between the shear modulus and damping ratio. The results indicate that the initial liquefaction assessment criteria for the loose and dense silts are a double-amplitude axial strain of 5% and an EPWP ratio of 1. The increase in the anti-liquefaction ability for the dense silt is more significant under lower confining pressures. The CSR of loose silt falls well within the results of the sandy silt and Fraser River silt, and the dense silt exhibits a higher liquefaction resistance than the sand-silt mixture. The relationships between the CSR and loading cycles were obtained at a failure strain of 1%. The EPWP development in the dense and loose silts complies with the "fast-stable" and "fast-gentle-sharp" growth modes, respectively. The power function model can effectively describe the EPWP growth characteristics of the dense silt. Finally, based on the liquefaction behaviour of silt, a suggestion for reinforcing silt slopes or foundations is proposed.

An Assessment of Changes in Bioclimatic Types in Sichuan Province, 1961-2010

Assessing the impact of climate change is important for ecosystem conservation and plant recovery, especially in climate sensitive regions. Various studies suggested that the KSppen classification is an effective method to depict climate change. However, these studies were restricted to large scales or of limited accuracy due to uncertainties in climate model projections. In addition, the impact of elevation on the shift of climate zones, as compared with other factors, is less emphasized. To address these issues we compiled the KSppen Climate Classification （period 1961-2olo） for the study area, Sichuan Province, China. The spatial resolution was selected as x km x x km. Sichuan Province may be characterized by 3 main climate classes and 1o subtypes. The east-west gradient of the climatic regimes in Siehuan is represented by the main climate classes, warm temperate climates （C）, snow climates （D） and polar climates （E）, at which the most abundant class is C. The most abundant subtype is snow climate with dry winter and cool summer （Dwe）. Shifts in K/Sppen climate classes reflect the observed trend of increasing temperature. Finally, the elevation showed an obvious impact on the distribution and the change of climate classes in Siehuan Province. The shift of areas covered by KSppen climate classes increases with elevation.

A Review on Researches of Active Tectonics—History,Progress and Suggestions

This paper reviews the history and progress of research on active tectonics in China and overseas.By giving a brief introduction on the history of active tectonic research in China and other countries,the paper sums up the process and development of quantitative investigation of active tectonics since the 1980s.The focus is on the main efforts and progress made in China on certain aspects of research,such as basic surveys and applied investigation of active tectonics,the study of theories related to regional active tectonics and their kinematics and geodynamics,surveys on coupling relations between deep and shallow structures,active fault surveys and prospecting and seismic hazard assessment in urban areas,as well as the efforts made using Quaternary geochronology.Furthermore,the paper looks back on Chinese quantitative investigation of active tectonics in China and sums up cognitions derived from studies on the determination of several basic and measurable parameters of active tectonics.These parameters include the length of fault and fault segmentation,coseismic slip and cumulative slip,fault slip rate,the sequence of paleoearthquake events and the time elapsed since the most recent event.At the same time,efforts and progress made in China on assessing the long-term seismic potential for active faults and evaluating the risk from potential active fault movement have been reviewed by summarizing research on developing theories,models,methods and the application of time-dependent seismic potential to probabilistic assessment,magnitude estimation for potential earthquakes on active faults,and the forecast of potential risk caused by active fault movement.Finally,in consideration of the realities and problems in the research of active tectonics in China,the authors put forward several suggestions for issues worthy of more attention for further investigation in the future.

Ecological Suitability Assessment and Introduction Experiment on Rosa damascena trigintipetala in Sichuan Province, China

This study comprehensively considered the climate, soil, terrain, and land-use type conditions suitable for Rosa damascena trigintipetala and further established an ecological suitability evaluation model of R. damascena triginffpetala in Sichuan Province, China, based on geographic information systems （GIS） and Agro-Ecological Zone （AEZ） models; then we assessed the different ecological suitability grades for this species in Sichuan Province of China and summarized the suitable land areas and spatial distribution pattern for R. damascena trigintipetala. The results show that the suitable areas （which contain highly suitable, generally suitable, and critically suitable areas） for R. damascena trigintipetala are 307.268×lO4 hm^2, which accounts for 6.34% of the total provincial area. Results also indicate that shrub land and open forest land are the major land-use types suitable for R. damascena trigintipetala, with the suitable areas of 303.162×lO4 hm2 （6.25% of the total provincial area）. An introduction test was conducted in one of the suitable areas, Xichang City, which demonstrated that R. damascena trigintipetala grows well at theexperimental sites. The quality of rose oil extracted from R. damascena trigintipetala planted in Xichang meets the Bulgaria Rose Oil Standard, thus verifying the accuracy and reliability of the ecological suitability assessment results.

Phantom-based evaluations of two binning algorithms for four-dimensional CT reconstruction in lung cancer radiation therapy

Objective: The purpose of this study was to evaluate the performance of the phase-binning algorithm and amplitude-binning algorithm for four-dimensional computed tomography(4DCT) reconstruction in lung cancer radiation therapy. Methods: Quasar phantom data were used for evaluation. A phantom of known geometry was mounted on a four-dimensional(4D) motion platform programmed with twelve respiratory waves(twelve lung patients trajectories) and scanned with a Philips Brilliance Big bore 16-slice CT simulator. The 4DCT images were reconstructed using both phase- and amplitude-binning algorithms. Internal target volumes(ITVs) of the phase- and amplitude-binned image sets were compared by evaluation of shape and volume distortions. Results: The phantom experiments illustrated that, as expected, maximum inhalation occurred at the 0% amplitude and maximum exhalation occurred at the 50% amplitude of the amplitude-binned 4DCT image sets. The amplitude-binned algorithm rendered smaller ITV than the phase-binning algorithm. Conclusion: The amplitude-binning algorithm for 4DCT reconstruction may have a potential advantage in reducing the margin and protecting normal lung tissue from unnecessary irradiation.

An evaluation of deep thin coal seams and water-bearing/resisting layers in the quaternary system using seismic inversion

Non-liner wave equation inversion,wavelet analysis and artificial neural networks were used to obtain stratum parameters and the distribution of thin coal seams.The lithology of the water-bearing/resisting layer in the Quaternary system was also predicted.The implementation process included calculating the well log parameters,stratum contrasting the seismic data and the well logs,and extracting,studying and predicting seismic attributes.Seismic inversion parameters,including the layer velocity and wave impedance,were calculated and effectively used for prediction and analysis.Prior knowledge and seismic interpretation were used to remedy a dearth of seismic data during the inversion procedure.This enhanced the stability of the inversion method.Non-linear seismic inversion and artificial neural networks were used to interpret coal seismic lithology and to study the water-bearing/resisting layer in the Quaternary system.Interpretation of the 1～2 m thin coal seams,and also of the water-bearing/resisting layer in the Quaternary system,is provided.The upper mining limit can be lifted from 60 m to 45 m.The predictions show that this method can provide reliable data useful for thin coal seam exploitation and for lifting the upper mining limit,which is one of the principles of green mining.

Experimental Evaluation of the Post-ultimate Strength Behavior of a Ship＇s Hull Girder in Waves

Experimental investigations into the collapse behavior of a box-shape hull girder subjected to extreme wave-induced loads are presented.The experiment was performed using a scaled model in a tank.In the middle of the scaled model,sacrificial specimens with circular pillar and trough shapes which respectively show different bending moment-displacement characteristics were mounted to compare the dynamic collapse characteristics of the hull girder in waves.The specimens were designed by using finite element(FE)-analysis.Prior to the tank tests,static four-point-bending tests were conducted to detect the load-carrying capacity of the hull girder.It was shown that the load-carrying capacity of a ship including reduction of the capacity after the ultimate strength can be reproduced experimentally by employing the trough type specimens.Tank tests using these specimens were performed under a focused wave in which the hull girder collapses under once and repetitive focused waves.It was shown from the multiple collapse tests that the increase rate of collapse becomes higher once the load-carrying capacity enters the reduction path while the increase rate is lower before reaching the ultimate strength.

In Vivo Anti-Inflammatory Assessment of Quillaja saponaria Mol. Extracts

Aqueous extracts from the native Chilean Quillaja saponaria tree are used orally and topically to treat lung inflammatory problems and toothache. This study aimed to corroborate their presumed anti-inflammatory activity, identify their active ingredients and validate their use. The topical anti-inflammatory activity of a commercial partially purified Quillaja saponin aqueous extract （Ultra Dry 100Q, UD）, the crude acid hydrolysate （H-100Q） of this material, its two most abundant sapogenins QA （quillaic acid） and PA （phytolaccagenic acid）, and two formulations containing QA were subjected to topical assays for the inhibition ofmurine ear inflammation elicited by AA （arachidonic acid） or TPA （phorbol ester）. The dose-dependent anti-inflammatory activity of QA was confirmed in both AA （maximal effect 92.1%） and TPA （maximal effect 62.2%） assays, and PA showed significant anti-inflammatory activity against AA （46.5%）. Two dermo pharmaceutical formulations containing 8% w/v QA as the active ingredient--a cream and a gel--also exhibited significant anti-inflammatory effects in the TPA （50.8%） and AA （39.5%） assays.

Risk Assessment of Veterinary Drug Residues： The Dietary Exposure Assessment of Benzylpenicillin and Tetracycline Residues in Pork Consumed on Filipino Market

Biological, physical and chemical agents, recognized as food safety hazards, cause potential risks in modem food productions. Although the use of antibiotics in intensive animal productions is impossible to avoid the presence and remaining amount of their residues in food, it is possible to reduce them by using the principles of good veterinary, good manufacturing practices, and continuous control of food and risk assessment approach. This study was conducted to determine exposure risk to antibiotic drug residues in pork consumed in the Philippines and aimed to estimate dietary exposure of benzylpenicillin and tetracycline residues by age and gender groups. Dietary modeling, validated method used, combines food consumption data with food chemical concentration data to estimate dietary exposure to food chemicals. The results had shown that the dietary exposure of benzylpenicillin and tetracycline residues for children from 1 to 〈 3 years old had the highest exposure followed by adolescents, adults and infants while males were significantly lower than females （P 〈 0.05）. This is the initial study to determine risk assessment of dietary exposure to antibiotic residue of different population of Filipino groups.

保持心底的真善美

学校开展“四评”活动,即学校评教育局、家长评学校、教师评校长、学生评教师。其中,“学生评教师”这一项,教师尤为看重。于是,许多老师变得极富亲和力,争先恐后地来到学生中间,和颜悦色,嘘寒问暖。不要以为学生不谙世事,其实他们心里都跟明镜似的,只有老师将他们视为有独立人格的人,他们才会将老师视为可敬仰可信赖的人。很自然地,师生之间的心理栅栏就消失了,师生关系变得融洽了、和谐了。有什么样的聪明教师,就有什么样的聪明学生。不过,这祥的聪明是否过于世故、过于圆滑了呢?
